"This is also for people who don't want the stigma, they may not believe in ghosts," said Condrey. "They don't want to move in and find out Andrea Yates drowned her children here in Houston or John Wayne Gacy buried 26 young men in the crawl space."

For $12 a pop, Condrey and his team access thousands of public records, some dating back to the 1800's, and let you know who's lived and died on your property.

"The law does say if someone asks, 'Was someone killed here?' the realtor is supposed to answer that honestly," said Nick Kremydas, CEO of the South Carolina Realtors Association.

Realtors say it can often be more difficult to sell a home perceived to be haunted or with a dark history, but that's not the case everywhere in South Carolina.

"Part of the tourism trade in Charleston, they do a lot of haunted tours, and these types of properties can have a lot of appeal," said Kremydas.

Whether you're a believer or not, most agree it's better to know -- if you can live with the truth that is.
